(b)
Using a dial indicator, measure the inside diameter
of the input shaft bushing.
Maximum inside diameter: 39.14 mm (1.5409 in.)
If the inside diameter exceeds the limit, replace the input
shaft.

Turn the ring and push it in to check the braking
action.
(b)
Measure the clearance between the synchronizer
ring back and the input shaft spline end.
Standard clearance: 1.15 − 1.85 mm
(0.0453 − 0.0728 in.)
Minimum clearance: 0.8 mm (0.031 in.)
If the clearance is less than the limit, replace the syn-
chronizer ring.
ASSEMBLY OF INPUT SHAFT
INSTALL SUN GEAR
(a)
Install the sun gear to the input shaft.
HINT: Make sure to install the sun gear in the correct
direction.
(b)

INSPECTION OF PLANETARY GEAR
1.
MEASURE PLANETARY PINION GEAR THRUST
CLEARANCE
Using a feller gauge, measure the planetary pinion
gear thrust clearance.
Standard clearance: 0.11 − 0.86 mm
(0.0043 − 0.0339 in.)
Maximum clearance: 0.86 mm (0.0339 in.)
If the clearance exceeds the limit, replace the planetary
gear assembly.
2.
CHECK OIL CLEARANCE OF PLANETARY PINION
GEAR
Using a dial indicator, measure the oil clearance of the
planetary pinion gear.
Standard clearance: 0.009 − 0.038 mm
(0.0004 − 0.0015 in.)
Maximum clearance: 0.038 mm (0.0015 in.)
If the clearance exceeds the limit, replace the planetary
gear assembly.
